Trailer Mounted System Advantages: 1. Large-Volume Foam Storage: 500-3000L integrated tanks provide 10-30 minutes sustained foam operations (vs trolley 100-200L = 5-10 min), Eliminates need for foam tender trucks or external foam supply in initial attack phase, Sufficient for complete Class B fire knockdown and vapor suppression in many scenarios. 2. Road Mobility: Towable behind fire apparatus or vehicles at highway speeds (50-80 km/h), Rapid inter-facility deployment or mutual aid response, Covers larger geographic areas than trolleys (limited to on-site pushing), Pre-positioning capability at strategic locations (refineries, airports, ports). 3. Higher Flow Capacity: Typically 500-2000 GPM (vs trolley 500-1000 GPM maximum), Delivers industrial-scale foam blanket suppression, Suitable for large storage tank fires, aircraft emergencies, marine incidents. 4. Complete Self-Contained Platform: Integrated foam tank, monitor, eductor, storage compartments all on single trailer, Arrives on-scene ready for immediate deployment with pre-loaded foam, Reduces crew workload and deployment time compared to assembling multiple components. 5. Stable Platform: Trailer chassis provides solid mounting base for high-flow monitor, Leveling jacks compensate for uneven ground, Less vibration and movement during operations vs trolley wheels.

Comparison: Trailer vs Trolley Monitors: Trailer: 500-2000 GPM, 500-3000L foam tank, road-towable, 800-1500kg, requires towing vehicle, 10-30 min foam duration. Trolley: 500-1000 GPM, 100-200L foam tank optional, push/pull on-site, 120-180kg, 2-3 person manual, 5-10 min foam duration. Trailer vs Fixed Foam Systems: Trailer: Mobile/redeployable, lower capital investment, flexible coverage, requires water supply connection. Fixed: Permanent installation, higher automation, dedicated foam proportioning, integrated with facility systems.

Selection Guidance: Choose Trailer Mounted Foam Systems for: Airport/aviation firefighting (aircraft aprons, hangars requiring rapid response), Industrial facilities with multiple hazard areas (refineries, petrochemical complexes), Marine/port fire protection (loading terminals, vessel firefighting support), Emergency response organizations covering large geographic areas, Facilities requiring mobile large-volume foam capability without permanent infrastructure. Choose Trolley Monitors for: Facility-specific tactical deployment within site boundaries, Supplementary coverage in areas beyond fixed monitor reach, Lower flow requirements (500-1000 GPM sufficient), Budget constraints (trolleys 40-50% less expensive than trailers), Frequent repositioning within confined areas (warehouses, tank farms). Choose Fixed Foam Systems for: Permanent hazard protection (storage tanks, loading racks, process areas), Automated fire detection/suppression integration, High-reliability applications requiring no manual intervention, Facilities with dedicated foam proportioning and distribution infrastructure.

Foam Tank Sizing Calculation Method: Step 1: Determine Required Application Duration Typical Requirements: Airport/aviation: 10-15 minutes (NFPA 403 aircraft hangar protection), Industrial tank fires: 15-20 minutes initial attack (transition to facility foam system), Loading rack fires: 10-15 minutes (sufficient for most spill fire scenarios), Emergency response: 20-30 minutes (allows extended operations before resupply). Step 2: Calculate Foam Concentrate Requirement Formula: Foam Concentrate (Liters) = Monitor Flow (LPM) × Duration (minutes) × Concentrate % ÷ 100. Example Calculations: 500 GPM (1893 LPM) Monitor, 3% AFFF, 15 minutes: 1893 × 15 × 0.03 = 851 liters required → Select 1000L tank. 1000 GPM (3785 LPM) Monitor, 3% AFFF, 10 minutes: 3785 × 10 × 0.03 = 1136 liters required → Select 1500L tank. 1500 GPM (5678 LPM) Monitor, 6% concentrate, 12 minutes: 5678 × 12 × 0.06 = 4088 liters required → Consider 2× trailers with 2000L tanks or single 3000L+ custom tank.

Tank Size Selection Guide by Flow Rate: 500 GPM (1893 LPM) Monitor: 500L tank = 8.8 minutes @ 3% (minimum for quick attack), 1000L tank = 17.6 minutes @ 3% (recommended for most applications), 1500L tank = 26.4 minutes @ 3% (extended operations, remote locations). 750 GPM (2839 LPM) Monitor: 1000L tank = 11.7 minutes @ 3% (adequate for initial attack), 1500L tank = 17.6 minutes @ 3% (recommended), 2000L tank = 23.5 minutes @ 3% (extended operations). 1000 GPM (3785 LPM) Monitor: 1500L tank = 13.2 minutes @ 3% (minimum recommended), 2000L tank = 17.6 minutes @ 3% (standard), 3000L tank = 26.4 minutes @ 3% (heavy industrial/airport). 1500 GPM (5678 LPM) Monitor: 2000L tank = 11.7 minutes @ 3% (absolute minimum), 3000L tank = 17.6 minutes @ 3% (recommended for high-flow applications). 2000 GPM (7571 LPM) Monitor: 3000L tank = 13.2 minutes @ 3% (minimum for very high flow systems), Consider dual-tank trailer or foam tender support for extended operations.

Application-Specific Recommendations: Airport/Aviation Firefighting: Requirement: NFPA 403 recommends 10-15 minutes foam supply for aircraft hangars. Typical System: 1000-1500 GPM monitor with 2000-3000L foam tank, Allows initial aircraft exterior foam blanket application + hangar floor coverage, Transition to airport foam trucks or hydrant foam system for sustained operations. Refinery/Petrochemical Tank Farms: Requirement: Initial attack 15-20 minutes before foam tender or facility system engagement. Typical System: 1000-1500 GPM monitor with 2000-3000L foam tank, Provides immediate response while mobilizing additional foam resources, Multiple trailers staged at strategic tank farm locations for mutual support. Loading Rack / Transfer Operations: Requirement: 10-15 minutes covers most spill fire scenarios (typical spills 100-500 m²). Typical System: 750-1000 GPM monitor with 1500-2000L foam tank, Sufficient for complete spill area foam blanket coverage, Can be resupplied from facility foam concentrate storage if extended operations needed. Emergency Response / Mutual Aid: Requirement: 20-30 minutes provides operational flexibility in unknown scenarios. Typical System: 750-1000 GPM monitor with 2000-3000L foam tank, Extended duration allows travel to scene + initial attack + sustained operations, Reduces dependency on immediate foam resupply coordination.

Towing Vehicle Requirements: Trailer Weight Considerations: Empty Trailer Weight (Typical Ranges): 500 GPM system with 500L tank: 800-1000 kg, 1000 GPM system with 1500L tank: 1000-1200 kg, 1500 GPM system with 2000L tank: 1200-1400 kg, 2000 GPM system with 3000L tank: 1400-1600 kg. Loaded Weight (With Foam Concentrate): Add 0.9-1.1 kg per liter of foam concentrate capacity (specific gravity ~0.9-1.1), Example: 2000L tank adds ~2000 kg when filled, Total Loaded Weight: 1200 kg trailer + 2000 kg foam = 3200 kg gross weight. Towing Capacity Requirements: Rule of Thumb: Towing vehicle should have rated towing capacity ≥ 1.5× loaded trailer weight (safety factor). Suitable Towing Vehicles by Trailer Size: Light Trailers (500-750 GPM, 500-1000L tank, loaded weight 1500-2500 kg): Fire apparatus with towing provision (2500-5000 kg capacity), Heavy-duty pickup trucks / SUVs (Toyota Hilux, Ford F-150, Land Cruiser with 3000-4500 kg towing capacity), Light commercial vehicles (3000-4000 kg capacity). Medium Trailers (1000 GPM, 1500-2000L tank, loaded weight 2500-3500 kg): Fire engines with dedicated towing coupling (most pumpers 4000-7000 kg towing capacity), Medium-duty trucks (Isuzu NPR, Hino 300 series, 4000-6000 kg capacity), Heavy SUVs/trucks (Ford F-250/350, Ram 2500/3500, 5000-7000 kg capacity).

Note: Customer responsible for final registration/compliance in destination jurisdiction, but we provide all necessary manufacturer documentation and can customize trailer to meet specific standards when specified during order.

Operational Considerations: Towing Speed: Typical trailer design speed: 80-100 km/h maximum (highway legal), Lower speeds (40-60 km/h) recommended for: Rough roads, Loaded trailer in emergency response (sloshing concerns, though baffled tanks minimize), Tight maneuvering in facility roads. Maneuverability: Turning Radius: Single axle trailers: Tight turning (important for facility roads, airport aprons), Tandem axle trailers: Wider turning radius (consider facility layout during selection). Reversing: Practice required for precise positioning, Consider storage/deployment locations accessible without extensive reversing.
